They allow safe current levels to flow and as soon as they detect an unsafe current level they will stop allowing current to flow through. The resistance levels within a PTC increase as the temperature does. They are used in applications where frequent overcurrents may take place such as within computers and various pieces of electrical equipment. Resettable fuse – resettable fuses can also be known as poly switch resettable PTCs fuses.Blade fuses display their ratings by showing a colour on their body. Another name for automotive fuses is blade fuses and they can come in a variety of different sizes. The majority of fuses in this class are rated for nothing more than about 32 volts but in some cases can rise up to around 42 volts. Automotive fuse – automotive fuses are a type of fuse class that is used to protect the wiring and electrical equipment that is found in vehicles.They come in a number of different sizes, voltage, and current ratings. Typically cartridge fuses are made of ceramic, glass, or porcelain materials.

They are cylindrical and have a contact point at either end of the fuse.

Cartridge fuse – a DC cartridge fuse is a low-cost safety device that is used in the protection of electrical circuits, machines, and appliances.

This may differ depending on what type of fuse is being used. The standard electrical for a fuse is shown below. Like any electrical component, fuses are represented by a symbol in electrical drawings. What is the electrical symbol for a fuse? If you would like to learn more about how fuses work then check out our article here. This is because the internals of a circuit breaker does not get destroyed in the event of an overcurrent. Circuit breakers are used in certain applications instead of fuses as when they trip you can simply reset them without replacing them. They are a cost-effective way of providing electrical protection to electrical systems. If fuses were not fitted the excess current could melt cable insulation and potentially damage other components within the circuit.įuses are used in nearly all electrical devices and circuits. Overcurrent can be caused within an electrical circuit by short circuits, electrical arcing, and similar electrical issues. They have an outer sheath that is used as a safety device to minimise arcing in the event of a severe overcurrent. The point at which a fuse will blow its conductive strip is called its breaking capacity. When the fuse blows it opens the electrical circuit and stops any current flow through the connected circuit or components.

A fuse is always fitted in series with the circuit/components that need protection from overcurrent. Fuses reduce the risk of electrocution and fire, they also protect wiring and components and minimise the amount of heat damage that could be caused. If the conductive strip melts within a fuse the circuit will break and prevent any current from flowing through. They are internally filled with a conductive strip that melts in the event of an excessive current passing through. What is a fuse?Ī fuse is a device built for the safety and protection of a circuit. In this article, we will start by looking at what a fuse actually is, we will look at the different types of fuses and their applications, and finally, we will answer some key questions associated with fuses. Knowing what a fuse actually is and what it does is a completely different matter. Generally, people know that from time to time a fuse may need replacing and can be one of the reasons why your electrical device may not power on. You have more than likely heard the term fuse mentioned when referring to any electrical device or circuit.
